1/9
Here's the proper explanation:
Since the vertex is (2,-1), the original equation will look like this: y=a*(x-2)^2-1
When the substitution happens we get to this:
0=a*(5-2)^2-1 then 1=a*(5-2)^2 -> 1=a*9
So, a=1/9! Written in another form:
1/9x^2-4/9x+4/9-1
Hope could help :)
Answer:
2/145
Step-by-step explanation:
The ratio of the number of Kentucky's representatives to the total number of representatives is
... 6/435 = 2/145
Answer:
No solutions
Step-by-step explanation:
If we try to solve this system for y at x = 1, we get an impossible situation:

Clearly, 1 ≠ -15, and we'll see that any value of x that we pick gives us two contradictory values for y, so this system has no solutions.
The answer is 3. 3 is the answer.
Answer:
y=-1/3x+1/2
the slope is -1/3 and the y intercept is where the line crosses the y axis, which in this case, is 1/2
